BACKGROUND 1. Technical Field

The present disclosure relates to a semiconductor device package and a method of manufacturing the same, and more particularly to a semiconductor device package including an antenna and a method of manufacturing the same.

2. Description of the Related Art

Wireless communication devices, such as cell phones, typically include antennas for transmitting and receiving radio frequency (RF) signals. Comparably, a wireless communication device includes an antenna and a communication module, each disposed on different parts of a circuit board. Under the comparable approach, the antenna and the communication module are separately manufactured and electrically connected together after being placed on the circuit board. Accordingly, separate manufacturing costs may be incurred for both components. Furthermore, it may be difficult to reduce a size of the wireless communication device to attain a suitably compact product design. To reduce the cost and package size, an Antenna-in-Package (AiP) approach is provided. In general, an organic substrate is used in an AiP system. However, due to the process constraint of the organic substrate, it is difficult to achieve fine-pitch (less than 15/15 μm), and the thickness of the organic substrate is relatively thick, which will hinder the miniaturization of the AiP system.

DETAILED DESCRIPTION

FIG. 1 illustrates a cross-sectional view of a semiconductor device package 1 in accordance with some embodiments of the present disclosure. The semiconductor device package 1 includes a carrier 10, circuit layers 11, 13, 14, interconnection structures 12 a, 12 b, an electronic component 15, electrical contacts 16 and package bodies 17, 18 and 19.

In some embodiments, the carrier 10 may be or include a glass substrate. In some embodiments, the carrier 10 may be or include an emitting device having one or more emitting components (e.g., an antenna, a light emitting device, a sensor or the like) disposed thereon. The carrier 10 may include conductive pad(s), trace(s), and interconnection(s) (e.g. via(s)). In some embodiments, the carrier 10 may include transparent material. In some embodiments, the carrier 10 may include opaque material. The carrier 10 includes a material having a dielectric constant (Dk) less than approximately 5. The carrier 10 includes a material having a Dk less than approximately 3. The carrier 10 includes a material having a loss tangent or dissipation factor (Df) less than approximately 0.005. The carrier 10 includes a material having a loss tangent or Df less than approximately 0.003. The carrier 10 has a surface 101, a surface 102 opposite to the surface 101 and a lateral surface 103 extending between the surface 101 and the surface 102. Compared to the organic substrate, it is easier to control the thickness of a glass carrier, which can facilitate the miniaturization of the semiconductor device package 1. In some embodiments, the thickness of the carrier 10 is about 400 μm. In some embodiments, a coefficient of thermal expansion (CTE) of the carrier 10 is in a range from about 0.5 to about 13. In some embodiments, the CTE of the carrier 10 is in a range from about 3.6 to about 8.5.

A conductive layer 10 p is disposed on the surface 102 of the carrier 10. In some embodiments, the conductive layer 10 p defines a patterned antenna, such as a directional antenna, an omnidirectional antenna, an antenna array. For example, the conductive layer 10 p defines a patch antenna. The conductive layer 10 p is, or includes, a conductive material such as a metal or metal alloy. Examples of the conductive material include gold (Au), silver (Ag), copper (Cu), platinum (Pt), Palladium (Pd), other metal(s) or alloy(s), or a combination of two or more thereof. In some embodiments, the conductive layer 10 p may be replaced by one or more light emitting devices or sensors.

The circuit layer 11 (or building-up circuit) has a surface 111 facing away from the carrier 10, a surface 112 opposite to the surface 111 and a lateral surface 113 extending between the surface 111 and the surface 112. The carrier 10 is disposed on the surface 112 of the circuit layer 11. The carrier 10 is connected to the surface 112 of the circuit layer 11 through an adhesive layer 10 a (e.g., a die attach film, DAF). The carrier 10 is spaced apart from the circuit layer 11. For example, there is a distance (e.g., a thickness of the adhesive layer 10 a) between the surface 101 of the carrier 10 and the surface 112 of the circuit layer 11. In some embodiments, the lateral surface 113 of the circuit layer 11 and the lateral surface 103 of the carrier 10 are noncoplanar or discontinuous. For example, the lateral surface 103 of the carrier 10 is recessed from the lateral surface 113 of the circuit layer 11. For example, a width of the carrier 10 is less than a width of the circuit layer 11.

The circuit layer 11 includes one or more conductive layers (e.g., redistribution layers, RDLs) 11 c and one or more dielectric layers 11 d. A portion of the conductive layer 11 c is covered or encapsulated by the dielectric layer 11 d while another portion of the conductive layer 11 c is exposed from the dielectric layer 11 d to provide electrical connections. In some embodiments, the exposed portion of the conductive layer 11 c is embedded within the adhesive layer 10 a. For example, the portion of the conductive layer 11 c disposed on the surface 112 of the circuit layer 11 is disposed within the adhesive layer 10 a. In some embodiments, the conductive layer 11 c may be or include one or more antenna patterns, light emitting devices, sensors or the like.

In some embodiments, the dielectric layer 11 d may include pre-impregnated composite fibers (e.g., pre-preg), Borophosphosilicate Glass (BPSG), silicon oxide, silicon nitride, silicon oxynitride, Undoped Silicate Glass (USG), any combination of two or more thereof, or the like. Examples of a pre-preg may include, but are not limited to, a multi-layer structure formed by stacking or laminating a number of pre-impregnated materials/sheets. In some embodiments, there may be any number of conductive layers 11 c depending on design specifications. In some embodiments, the conductive layer 11 c is formed of or includes Au, Ag, Cu, Pt, Pd, or an alloy thereof.

The package body 17 is disposed on the surface 112 of the circuit layer 11. The package body 17 covers the carrier 10 and the conductive layer 10 p. The package body covers the surface 102 and the lateral surface 103 of the carrier 10 and a lateral surface of the adhesive layer 10 a. In some embodiments, the package body 17 has a lateral surface 173 substantially coplanar with the lateral surface 113 of the circuit layer 11. The lateral surface 103 of the carrier 10 is recessed from the lateral surface 173 of the package body 17. For example, there is a distance between the lateral surface 103 of the carrier 10 and the lateral surface 173 of the package body 17. In some embodiments, the package body 17 includes an epoxy resin including fillers, a molding compound (e.g., an epoxy molding compound or other molding compound), a polyimide, a phenolic compound or material, a material including a silicone dispersed therein, or a combination thereof.

In some embodiments, the interconnection structures 12 a define an antenna structure. The interconnection structure 12 a is, or includes, a conductive material such as a metal or metal alloy. Examples of the conductive material include Au, Ag, Cu, Pt, Pd, or an alloy thereof.

The package body 18 is disposed on the surface 111 of the circuit layer 11. The package body 18 covers the interconnection structures 12 a. In some embodiments, the package body 18 has a lateral surface 183 substantially coplanar with the lateral surface 113 of the circuit layer 11. In some embodiments, the package body 18 includes an epoxy resin including fillers, a molding compound (e.g., an epoxy molding compound or other molding compound), a polyimide, a phenolic compound or material, a material including a silicone dispersed therein, or a combination thereof.

The circuit layer 13 (or building-up circuit) is disposed on the package body 18. The circuit layer 13 has a dielectric layer 13 d and a conductive layer 13 c. In some embodiments, the dielectric layer 13 d may include the same material as the dielectric layer 11 d. Alternatively, the dielectric layer 13 d and the dielectric layer 11 d may include different materials. The conductive layer 13 c is disposed on a surface of the dielectric layer 11 d facing the circuit layer 11. The conductive layer 13 c is covered or encapsulated by the package body 18. The conductive layer 13 c is electrically connected to the interconnection structures 12 a. The conductive layer 13 c is in contact with the interconnection structures 12 a. In some embodiments, there may be any number of conductive layers 13 c depending on design specifications.

One or more interconnection structures 12 b (e.g., conductive pillars or conductive elements) are disposed on a surface of the circuit layer 13 facing away from the circuit layer 11. The interconnection structures 12 b are electrically connected to the circuit layer 13. The interconnection structure 12 b is, or includes, a conductive material such as a metal or metal alloy. Examples of the conductive material include Au, Ag, Cu, Pt, Pd, or an alloy thereof.

The package body 19 is disposed on the surface of the circuit layer 13 facing away from the circuit layer 11. The package body 19 covers the interconnection structures 12 b and the electronic component 15. In some embodiments, the package body 19 has a lateral surface substantially coplanar with the lateral surface of the circuit layer 13. In some embodiments, the package body 19 includes an epoxy resin including fillers, a molding compound (e.g., an epoxy molding compound or other molding compound), a polyimide, a phenolic compound or material, a material including a silicone dispersed therein, or a combination thereof.

The circuit layer 14 (or building-up circuit) is disposed on the package body 19. The circuit layer 14 has a dielectric layer 14 d and a conductive layer 14 c. In some embodiments, the dielectric layer 14 d may include the same material as the dielectric layer 11 d. Alternatively, the dielectric layer 14 d and the dielectric layer 11 d may include different materials. The conductive layer 13 c is disposed on a surface of the dielectric layer 14 d facing away from the circuit layer 13. The conductive layer 14 c is electrically connected to the interconnection structures 12 b. In some embodiments, there may be any number of conductive layers 14 c depending on design specifications.

The electronic component 15 is disposed on the surface of the circuit layer 14 facing the circuit layer 13. The electronic component 15 may be an active electronic component, such as an integrated circuit (IC) chip or a die. The electronic component 15 has a backside surface bonded or attached to the surface of the circuit layer 14 by an adhesion layer 15 a (e.g., DAF). The electronic component 15 has an active surface facing the circuit layer 13 and electrically connected to the circuit layer 13 through the interconnection structures 15 c (e.g., conducive pillars).

The electrical contacts 16 are disposed on the conductive layer 14 c exposed from the dielectric layer 14 d. In some embodiments, the electrical contacts 16 may include solder or other suitable material(s).

In some embodiments, the lateral surface 103 of the carrier 10 may be coplanar with the lateral surface 113 of the circuit layer 11. For example, the lateral surface 103 of the carrier 10 is exposed from the package body 17. Such structure may be formed by: (i) providing a glass wafer; (ii) forming the circuit layers 11, 13, 14, the interconnection structures 12 a, 12 b and the package bodies 17, 18, 19 and the electronic component 15 on the glass wafer; and (iii) performing a singulation through the circuit layers 11, 13, 14, the package bodies 17, 18, 19 and the carrier wafer. To meeting the criterion of the performance of the antenna structure, the glass wafer should select a material having a relatively low Dk (e.g., less than 5). However, a glass wafer having a relatively low Dk would have a relatively low CTE as well (e.g., less than 13). Due to a CTE mismatch between the glass wafer and the package body 17 (e.g., the package body generally has a CTE greater than 20), the warpage issues would occur. As the size of the glass wafer increases, the warpage issue becomes severer, which may result in the crack or damage of the glass wafer.

In accordance with the embodiments as shown in FIG. 1 , the lateral surface 103 of the carrier 10 is recessed from the lateral surface 111 of the circuit layer 11. Such structure may be formed by (detailed operations would be described later): (i) performing a singulation for a glass wafer to divide the glass wafer into a plurality glass carriers (e.g., the carrier 10 as shown in FIG. 1 ); (ii) forming the circuit layers 11, 13, 14, the interconnection structures 12 a, 12 b and the package bodies 17, 18, 19 and the electronic component 15; and (iii) attaching the carrier 10 on the circuit layer 11 through the adhesive layer 10 a. Since the size of the divided glass carrier is much less than that of the glass wafer, the warpage issue can be significantly mitigated. In addition, since it is unnecessary to select a material of the carrier 10 having a higher CTE to be close to the CTE of the package body 17, materials having lower CTE (also having lower Dk) can be selected as the carrier 10. This would enhance the performance of the antenna structure of the semiconductor device package 1. Furthermore, the thickness of the carrier 10 can be reduced as well, which would facilitate the miniaturization of the semiconductor device package 1.

FIG. 2 illustrates a cross-sectional view of a semiconductor device package 2 in accordance with some embodiments of the present disclosure. The semiconductor device package 2 is similar to the semiconductor device package 1 as shown in FIG. 1 , and one of the differences therebetween is that in FIG. 2 , a width of the adhesive layer 10 a is greater than a width of the carrier 10. For example, a lateral surface of the adhesive layer 10 a is substantially coplanar with the lateral surface 113 of the circuit layer 11. For example, the lateral surface 103 of the carrier 10 is recessed from the lateral surface of the adhesive layer 10 a. This would increase the accuracy of the alignment between the carrier 10 and the circuit layer 11 during the manufacturing process.

The semiconductor device package 3 is similar to the semiconductor device package 1 as shown in FIG. 1 , and the differences therebetween are described below.

In some embodiments, a width of the protection layer 57 is substantially the same as a width of the carrier 10. For example, a lateral surface of the protection layer 57 is substantially coplanar with the lateral surface 103 of the carrier 10. In accordance with the embodiments of FIG. 5A, replacing the package body (e.g., a molding compound) with the protection layer 57 can reduce the time and cost for manufacturing the semiconductor device package 5A. In addition, the thickness of the semiconductor device package 5A can be reduced as well.

FIG. 5B illustrates a cross-sectional view of a semiconductor device package 5B in accordance with some embodiments of the present disclosure. The semiconductor device package 5B is similar to the semiconductor device package 5A as shown in FIG. 5A, and one of the differences is that a width of the adhesive layer 10 a is greater than a width of the carrier 10. For example, a lateral surface of the adhesive layer 10 a is substantially coplanar with the lateral surface 113 of the circuit layer 11. For example, the lateral surface 103 of the carrier 10 is recessed from the lateral surface of the adhesive layer 10 a. This would increase the accuracy of the alignment between the carrier 10 and the circuit layer 11 during the manufacturing process.

FIG. 5C illustrates a cross-sectional view of a semiconductor device package 5C in accordance with some embodiments of the present disclosure. The semiconductor device package 5C is similar to the semiconductor device package 1 as shown in FIG. 1 , and the differences therebetween are described below.

In FIG. 5C, the package body 17 is omitted. A protection layer (or protection film) 58 covers the surface 112 of the circuit layer 11, the lateral surface 103 and the surface 102 of the carrier 10. The protection layer 58 has a first lateral surface coplanar with the lateral surface 113 of the circuit layer 11 and a second lateral surface recessed from the first lateral surface.

FIG. 5D illustrates a cross-sectional view of a semiconductor device package 5D in accordance with some embodiments of the present disclosure. The semiconductor device package 5D is similar to the semiconductor device package 5C as shown in FIG. 5C, and one of the differences is that a width of the adhesive layer 10 a is greater than a width of the carrier 10. For example, a lateral surface of the adhesive layer 10 a is substantially coplanar with the lateral surface 113 of the circuit layer 11. For example, the lateral surface 103 of the carrier 10 is recessed from the lateral surface of the adhesive layer 10 a. This would increase the accuracy of the alignment between the carrier 10 and the circuit layer 11 during the manufacturing process.

FIG. 6 illustrates a cross-sectional view of a semiconductor device package 6 in accordance with some embodiments of the present disclosure. The semiconductor device package 6 is similar to the semiconductor device package 3 as shown in FIG. 3 , and the differences therebetween are described below.

The part 6A and the part 6B may be manufactured individually and then connected to each other through electrical contacts 61 s (e.g., solder balls). This would increase the yield rate of the semiconductor device package 6. In some embodiments, an underfill 61 h may be disposed between the part 6A and the part 6B to cover the electrical contacts 61 s. In some embodiments, a width of the part 6A is the same as a width of the part 6B. Alternatively, the width of the part 6A may be greater than or less than the width of the part 6B depending on design specifications.

As used herein, the terms “substantially,” “substantial,” “approximately,” and “about” are used to denote and account for small variations. For example, when used in conjunction with a numerical value, the terms can refer to a range of variation of less than or equal to ±10% of that numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. As another example, a thickness of a film or a layer being “substantially uniform” can refer to a standard deviation of less than or equal to ±10% of an average thickness of the film or the layer, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. The term “substantially coplanar” can refer to two surfaces within micrometers of lying along a same plane, such as within 40 within 30 within 20 within 10 or within 1 μm of lying along the same plane. Two surfaces or components can be deemed to be “substantially perpendicular” if an angle therebetween is, for example, 90°±10°, such as ±5°, ±4°, ±3°, ±2°, ±1°, ±0.5°, ±0.1°, or ±0.05°. When used in conjunction with an event or circumstance, the terms “substantially,” “substantial,” “approximately,” and “about” can refer to instances in which the event or circumstance occurs precisely, as well as instances in which the event or circumstance occurs to a close approximation.

As used herein, the singular terms “a,” “an,” and “the” may include plural referents unless the context clearly dictates otherwise. In the description of some embodiments, a component provided “on” or “over” another component can encompass cases where the former component is directly on (e.g., in physical contact with) the latter component, as well as cases where one or more intervening components are located between the former component and the latter component.

As used herein, the terms “conductive,” “electrically conductive” and “electrical conductivity” refer to an ability to transport an electric current. Electrically conductive materials typically indicate those materials that exhibit little or no opposition to the flow of an electric current. One measure of electrical conductivity is Siemens per meter (S/m). Typically, an electrically conductive material is one having a conductivity greater than approximately 10⁴ S/m, such as at least 10⁵ S/m or at least 10⁶ S/m. The electrical conductivity of a material can sometimes vary with temperature. Unless otherwise specified, the electrical conductivity of a material is measured at room temperature.

Additionally, amounts, ratios, and other numerical values are sometimes presented herein in a range format. It can be understood that such range formats are used for convenience and brevity, and should be understood flexibly to include not only numerical values explicitly specified as limits of a range, but also all individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly specified.
